Subject: [PATCH] manually handle NUL unicode in g_utf8_get_next_char_validated
A change in GLib 2.63 broke some assumptions in Irssi that the null-byte
NUL / U+0000 is a valid Unicode character. This would occur when the
user types Ctrl+Space. As a result, the input loop never manages to
process the NUL-byte (and any other user input that follows, ever).
This patch adds a manual check that properly advances the input loop if
GLib returns -2 (incomplete character) despite the length being positive
and a NUL is in first position.
Fixes #1180
